Description

Technical Field

[0001] This invention relates to the field of battery swapping, and particularly to a charging connector device, a charging rack, and a battery swapping station including the same. Background Technology

[0002] Currently, vehicle exhaust emissions remain a significant contributor to environmental pollution. To address this issue, natural gas vehicles, hydrogen fuel cell vehicles, solar-powered vehicles, and electric vehicles have been developed to replace gasoline-powered cars. Among these, electric vehicles hold the most promise. Current electric vehicles primarily fall into two categories: direct-charging and fast-swapping. Due to limitations in charging time and location, many new energy electric vehicles are gradually adopting a fast-battery swapping system for refueling.

[0003] When replacing the battery in an electric vehicle, the battery swapping equipment removes the depleted battery from the vehicle and transfers it to the battery transfer equipment. The battery transfer equipment then transfers the depleted battery to the charging rack for charging. Afterward, the battery transfer equipment removes a fully charged battery from the charging rack and transfers it to the battery swapping equipment, which then installs the fully charged battery into the electric vehicle. For charging the depleted battery, the electrical connectors on the charging rack must be aligned and connected to the battery terminal connectors on the battery pack before charging can begin.

[0004] In the prior art, Chinese invention patent authorization announcement number CN202772633U discloses an electric vehicle on-board power battery charging platform. This solution utilizes the downward force applied to the mounting seat during the process of placing the battery pack downward on the bracket. Through the cooperation of the inclined sliding groove, the rollers under the mounting seat, the sliding rail and the slider that realize the sliding connection of the mounting seat on the bracket, the vertical movement of the battery pack is converted into the horizontal movement of the mounting seat, thereby realizing the electrical connection. However, since the battery pack only contacts one end of the mounting seat, the mounting seat is prone to tilting during the process of being pressed down by the battery pack, resulting in mechanical jamming. Summary of the Invention

[0005] The present invention addresses the technical problem in the prior art where the mounting base is prone to tilting during the pressing process of the battery pack, resulting in mechanical jamming. The invention provides a charging connector device, a charging rack assembly, and a battery swapping station including the present invention, which is less prone to mechanical jamming during use.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A charging connector device is disposed on the frame of a charging rack, including an electrical connector assembly for electrical connection with a battery terminal electrical connector of a battery pack, the charging connector device further comprising:

[0008] Connecting base, used for connecting to the frame;

[0009] A rotating disk having a connecting end for rotatably connecting with the connecting seat and a carrying end for carrying a battery pack, the rotating disk being switchable between an initial state and a carrying state;

[0010] Mounting base, on which the electrical connector assembly is provided, the mounting base being movably connected to the rotating disk and the connecting base respectively via a linkage mechanism;

[0011] A reset component is disposed on the connecting base to provide a force to the rotating disk to switch it from a load-bearing state to an initial state;

[0012] When the rotating disk is not carrying a battery pack, the rotating disk is in its initial state under the force of the reset component, and the mounting base is in its initial position relative to the rotating disk under the drive of the reset component.

[0013] When the rotating disk carries the battery pack, the rotating disk overcomes the force of the reset component and is in a bearing state. The mounting base is in a docking position relative to the rotating disk under the drive of the linkage mechanism, so that the electrical connector assembly is electrically connected to the battery terminal electrical connector of the battery pack.

[0014] In this solution, the charging connector device rotates the rotating disk around its connection end by pressing down the battery pack. Then, through a linkage mechanism, the rotating disk's flipping motion is converted into the movement of the mounting base moving closer to or away from the rotating disk's bearing end. This ultimately achieves automatic mechanical docking of the charging connector device, enabling the electrical connector assembly to connect with the battery pack's electrical connector. Compared to existing technologies that convert vertical movement into horizontal movement of the mounting base to achieve electrical connection, this solution has a rotating point, making it more stable during state switching and less prone to mechanical jamming during use.

[0015] Preferably, when the battery pack is detached from the bearing end, the rotating disk rotates upward with the connecting end as the rotation point, and the mounting base moves away from the bearing end of the rotating disk under the force provided by the reset assembly;

[0016] When the battery pack is placed on the support end, the rotating disk rotates downward with the connection end as the rotation point, and the mounting base moves towards the support end of the rotating disk under the force provided by the linkage mechanism, so that the electrical connector assembly is electrically connected to the battery end electrical connector of the battery pack.

[0017] Preferably, the linkage mechanism includes a linkage mechanism and a horizontal moving mechanism, and the mounting base is slidably connected to the rotary disk through the horizontal moving mechanism;

[0018] The first end of the linkage mechanism is rotatably connected to the bearing end of the rotating disk, and the second end of the linkage mechanism is rotatably connected to the mounting base;

[0019] During the process of the rotating disk switching from the initial state to the load-bearing state, the linkage mechanism converts the rotating disk's flipping motion into a force that moves the mounting base from the initial position to the docking position.

[0020] In this solution, the linkage mechanism and the horizontal moving mechanism work together to achieve the effect of pressing the battery pack down onto the rotating disk, causing the electrical connector assembly and the battery end electrical connector of the battery pack to approach each other until they are connected.

[0021] Preferably, the linkage mechanism includes:

[0022] A first connecting rod and a second connecting rod, wherein the first end of the first connecting rod is rotatably connected to the bearing end of the rotating disk, the second end of the first connecting rod is rotatably connected to the first end of the second connecting rod, and the second end of the second connecting rod is rotatably connected to the mounting base;

[0023] The connection between the first link and the second link is slidably connected to the connecting seat.

[0024] In this solution, when the bearing end carries a battery pack, the rotating disk rotates, causing the first connecting rod to rotate. At the connection between the first and second connecting rods, the connecting rod slides relative to the connecting seat, which in turn transforms into the movement of the mounting seat toward the bearing end.

[0025] Preferably, when the rotating disk switches between the initial state and the load-bearing state, the angle between the first link and the second link toward the mounting base is always less than or equal to 90°.

[0026] In this solution, the aforementioned included angle setting allows the rotating disk to rotate when the bearing end carries a battery pack. This rotation causes the first connecting rod to rotate towards the bearing end, thereby causing the connection between the first and second connecting rods to slide relative to the connecting seat. This makes the connection between the first and second connecting rods closer to the bearing end, and then the second connecting rod causes the mounting seat to slide relative to the rotating disk. Ultimately, this converts the rotation of the rotating disk into the movement of the mounting seat towards the bearing end.

[0027] Preferably, the linkage mechanism further includes a sliding guide structure disposed on the connecting seat, wherein the connection between the first link and the second link is slidably connected to the sliding guide structure.

[0028] In this design, the sliding guide structure guides the movement of the connection between the first and second links. When the first link is subjected to force, the sliding guide structure can be used to drive the mounting base to move horizontally along the rotating disk, thus successfully realizing the mechanical automatic electrical connection function of the charging connector device. At the same time, since the linkage mechanism is located between the connecting base and the rotating disk, the space at this location is fully utilized, thereby reducing the overall size of the charging connector device.

[0029] Preferably, the sliding guide structure includes a guide member disposed on the connecting seat, the guide member having a strip-shaped guide hole, the connection point of the first connecting rod and the second connecting rod being located within the guide hole and movable along the length direction of the guide hole.

[0030] In this design, the guide hole of the guide member guides the movement at the connection between the first and second connecting rods. This allows the force applied to the first connecting rod to be converted into a force that drives the mounting base to move horizontally along the rotating disk, thus smoothly realizing the automatic mechanical electrical connection function of the charging connector device. Furthermore, since the linkage mechanism is located between the connecting base and the rotating disk, the space in this area is fully utilized, thereby reducing the overall size of the charging connector device. Additionally, the sliding guide structure is simple, further simplifying the overall structure of the charging connector device.

[0031] Preferably, the connecting seat includes a base plate, the guide member is disposed on the base plate, and the length direction of the guide hole is parallel to the plane of the base plate.

[0032] In this solution, the above-mentioned structural design helps to reduce the volume of the charging connector device in the vertical direction.

[0033] Preferably, the horizontal moving mechanism includes a guide rod and a slider that are slidably engaged, the guide rod and the slider being respectively connected to the rotary disk and the mounting base.

[0034] In this design, a matching guide rod and slider are used as the horizontal movement mechanism, which is simple in structure and thus helps to simplify the overall structure of the charging connector device.

[0035] Preferably, there are at least two horizontal moving mechanisms, and the at least two horizontal moving mechanisms are respectively disposed at both ends of the mounting base.

[0036] In this scheme, at least two horizontal moving mechanisms are set up to increase the number of connection points between the mounting base and the rotating disk, which helps to improve the stability and reliability of the mounting base when moving between the initial position and the docking position.

[0037] Preferably, there are at least two linkage mechanisms, which are disposed between the connecting seat and the rotating disk.

[0038] In this scheme, at least two linkage mechanisms are set up, which helps to improve the stability and reliability of the rotating disk when switching between the initial state and the load state, and reduces the probability of the rotating disk tilting.

[0039] Preferably, along the horizontal direction, the linkage mechanism is located between at least two of the horizontal moving mechanisms.

[0040] In this design, the linkage mechanism is positioned between at least two horizontal moving mechanisms, making reasonable use of the space between the at least two horizontal moving mechanisms and improving the compactness of the charging connector device.

[0041] Preferably, the mounting base is disposed between the bearing end and the connecting end of the rotating disk, and the two ends of the reset assembly are respectively connected to the connecting base and the mounting base to apply a force to the mounting base toward the bearing end away from the rotating disk.

[0042] In this solution, the reset component is located between the connecting seat and the mounting seat. When the force of the battery pack on the bearing end is removed, the reset component acts on the mounting seat, causing the mounting seat to move, and then, under the action of the linkage mechanism, it drives the rotating disk to rotate until it returns to the initial state.

[0043] Preferably, the reset assembly includes an elastic element, and the elastic element is in a stretched state when the rotating disk is in its initial state.

[0044] In this scheme, when the force of the battery pack on the bearing end is removed, the elastic element provides a force to the bearing end of the mounting seat away from the rotating disk. The mounting seat moves and drives the rotating disk to rotate, eventually bringing the mounting seat to the initial position and the rotating disk to the initial state.

[0045] Preferably, the mounting base is provided with a connecting portion extending toward the connecting seat, and the end of the connecting portion away from the mounting base is rotatably connected to the linkage mechanism, and the connecting seat includes a vertically arranged enclosure plate;

[0046] The two ends of the elastic element are respectively connected to the enclosure and the connecting part, and the elastic element is in a stretched state when the rotating disk is in the initial state, so as to apply a force to the connecting part toward the bearing end away from the rotating disk.

[0047] In this solution, the two ends of the reset component are connected to the enclosure of the connector and the mounting base respectively, which makes the connection more convenient, simplifies the overall structure of the charging connector device, and does not occupy additional space in the height direction of the charging connector device, thus reducing the overall height of the charging connector device.

[0048] Preferably, the two ends of the reset component are respectively located at the bearing end of the rotating disk and the connecting seat, so as to apply a force to the bearing end of the rotating disk toward the connecting seat.

[0049] In this solution, the reset component is located between the bearing end of the rotating disk and the connecting seat. When the force of the battery pack on the bearing end is removed, the reset component acts on the bearing end, causing the rotating disk to move, which in turn drives the mounting seat to move under the action of the linkage mechanism and the horizontal moving mechanism.

[0050] Preferably, the reset assembly includes an elastic element, and the elastic element is in a compressed state when the rotating disk is in a load-bearing state.

[0051] In this solution, when the force of the battery pack on the bearing end is removed, the elastic element provides a force to the bearing end of the bearing disk to move away from the connecting seat, so that the rotating disk can switch to the initial state and the mounting seat can switch to the initial position.

[0052] Preferably, there are two elastic elements, which are arranged in the same direction between the connecting seat and the rotating disk.

[0053] In this solution, by setting two elastic elements, multi-point elastic support can be achieved between the rotating disk and the connecting seat, improving the stability of the elastic connection between the rotating disk and the connecting seat, making the rotating disk less prone to tilting, thereby improving the reliability of the electrical connection between the electrical connector assembly and the battery pack.

[0054] Preferably, the rotating disk comprises:

[0055] The disc body has a receiving hole for the mounting base to pass through, and the connecting end and the bearing end are the two ends of the disc body, respectively;

[0056] An adapter plate is disposed at the receiving hole of the disc body, and the adapter plate is recessed toward the connecting seat to form a mounting area into which the mounting seat portion extends.

[0057] In this design, the mounting base extends below the receiving hole via an adapter plate. This reduces the volume of the charging connector device in the height direction, allowing the position of the electrical connector assembly to match the position of the battery terminal electrical connector of the battery pack. It also provides some protection for the structure where the mounting base extends below the disk.

[0058] Preferably, the adapter plate includes a first connecting plate and a second connecting plate that are connected to each other at a preset angle. The end of the first connecting plate away from the second connecting plate is connected to the receiving hole of the disc body, and the second connecting plate is located on the side of the disc body closer to the connecting seat. The mounting seat is connected to the second connecting plate through the horizontal moving mechanism and partially extends between the disc body and the second connecting plate.

[0059] In this design, the aforementioned adapter plate has a simple structure and is easy to manufacture. Meanwhile, the mounting base extends below the receiving hole, which, on the one hand, helps reduce the volume of the charging connector device in the vertical direction, allowing the position of the electrical connector assembly to match the position of the battery terminal electrical connector of the battery pack; on the other hand, it provides protection for the horizontal movement mechanism.

[0060] Preferably, the connecting seat includes a base plate and a surrounding plate circumferentially disposed on the base plate, the base plate and the surrounding plate together forming a receiving cavity, and the rotating disk is disposed at the opening of the receiving cavity.

[0061] In this design, the enclosure protects the internal structure of the charging connector device.

[0062] Preferably, the rotating disk is provided with a bending part, which is located at the connecting end of the rotating disk, and the bending part is rotatably connected to the surrounding plate of the connecting seat through a connecting pin.

[0063] In this solution, reliable rotation between the rotating disk and the connecting seat can be achieved through the connecting pin. The structure is simple and easy to assemble, which helps to ensure that the rotating disk can reliably switch between the initial state and the load-bearing state, thereby improving the reliability of the charging connector device in charging the battery pack.

[0064] Preferably, the bent portion is provided with a first connecting hole, the connecting seat is provided with a second connecting hole, and both ends of the connecting pin are surrounded by circumferential flanges. The connecting pin passes through the first connecting hole and the second connecting hole, so that the bent portion and the connecting seat are located between the two circumferential flanges.

[0065] In this design, the circumferential flange of the connecting pin can limit the gap or relative position between the rotating disk and the connecting seat, preventing the rotating disk from being stuck or its movement from being obstructed due to the rotating disk abutting against the connecting seat during the rotation of the rotating disk relative to the connecting seat. This helps to ensure that the rotating disk can reliably switch between the initial state and the load-bearing state, and further improves the reliability of the charging connector device in charging the battery pack.

[0066] Preferably, the charging connector device further includes two liquid cooling assemblies for connecting to the battery end liquid cooling assembly of the battery pack, the two liquid cooling assemblies being disposed on the mounting base and located on both sides of the electrical connector assembly.

[0067] In this solution, both the liquid cooling component and the electrical connector component are mounted on the mounting base, so that when the battery-side electrical connector is connected to the electrical connector component, the battery-side liquid cooling component can also be connected to the liquid cooling component at the same time.

[0068] Preferably, the two ends of the connecting seat are provided with connecting ear plates extending horizontally in opposite directions. The connecting ear plates are provided with first position adjustment holes. The connecting ear plates are detachably connected to at least one of a plurality of second position adjustment holes on the frame through the first position adjustment holes and connecting components.

[0069] In this solution, the connection ear plate facilitates the connection with the frame. The connection ear plate is provided with a first position adjustment hole. By cooperating with the first position adjustment hole and the second position adjustment hole, the position of the charging connector device on the frame can be adjusted more easily to accommodate battery packs of different sizes, thereby expanding the applicability of the charging rack.

[0070] The present invention also provides a charging stand, which includes a frame and the above-mentioned charging connector device, wherein the charging connector device is connected to the frame.

[0071] Preferably, the frame includes at least two brackets for supporting the battery pack, and a charging compartment for accommodating the battery pack is formed between two adjacent brackets in the height direction. The charging connector device is provided in a one-to-one correspondence with the charging compartment and is connected to the bracket.

[0072] In this solution, the charging connector device is connected to the bracket, and the positions of the charging connector device and the bracket are relatively fixed. When the battery pack is placed in place on the bracket from top to bottom, the corresponding part of the battery pack will also be placed in place on the bearing end of the rotating disk. At the same time, the rotating disk switches from the initial state to the bearing state, realizing a reliable connection between the electrical connector assembly of the charging connector device and the battery end electrical connector of the battery pack.

[0073] Preferably, along the first direction, the bracket is provided with at least two sets of second position adjustment holes, and the first position adjustment hole of the charging connector device is detachably connected to at least one set of second position adjustment holes via a connecting component;

[0074] The first direction is the mating direction between the battery terminal electrical connector and the electrical connector assembly.

[0075] In this solution, the position of the charging connector device can be easily adjusted through the first position adjustment hole and the second position adjustment hole to adapt to battery packs of different sizes, thereby expanding the applicability of the charging connector device.

[0076] The present invention also provides a battery swapping station, which includes the above-mentioned charging rack.

[0077] The positive and progressive effects of this invention are as follows:

[0078] In the charging connector device of the present invention, the rotating disk is rotated around its connection end by pressing down the battery pack. Then, the flipping motion of the rotating disk is converted into the movement of the mounting base moving closer to or away from the bearing end of the rotating disk by the linkage mechanism. Finally, the automatic mechanical docking of the charging connector device is realized, so that the electrical connector assembly and the electrical connector at the battery pack end are electrically connected. Compared with the prior art, which realizes electrical connection by converting the vertical movement into the horizontal movement of the mounting base, the structure of this solution has a rotation point, which is more stable when switching states and less prone to mechanical jamming during use.

Detailed Implementation

[0096] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0097]

Example 1

[0098] like Figure 1-12 As shown, this embodiment discloses a charging connector device 100, which is disposed on the frame 200 of the charging rack. The charging connector device 100 is used to connect an external power source to the battery terminal electrical connector of the charger and the battery pack. In this embodiment, the external power source is the charger, and the charger charges the battery pack through the charging connector device 100. The specific structure of the charging connector device 100 will be described in detail below.

[0099] like Figure 1-12 As shown, the charging connector device 100 includes an electrical connector assembly 10 for electrical connection with the battery terminal electrical connector of the battery pack, a connecting seat 20, a rotating disk 30, a mounting seat 40, and a reset assembly. The connecting seat 20 is connected to the frame 200. The rotating disk 30 has a connecting end 302 for rotatable connection with the connecting seat 20 and a supporting end 301 for supporting the battery pack. The rotating disk 30 can switch between an initial state and a supporting state. The aforementioned electrical connector assembly 10 is mounted on the mounting seat 40, and the mounting seat 40 is movably connected to the rotating disk 30 and the connecting seat 20 respectively via a linkage mechanism. The reset assembly is disposed on the connecting seat 20 and provides a force to the rotating disk 30 to switch it from the supporting state to the initial state. When the rotating disk 30 is not supporting the battery pack, the rotating disk 30 is in the initial state under the force of the reset assembly, and the mounting seat 40 is in the initial position relative to the rotating disk 30 under the action of the reset assembly. When the rotating disk 30 carries the battery pack, the rotating disk 30 is in a bearing state against the force of the reset component. The mounting base 40 is in a docking position relative to the rotating disk 30 under the drive of the linkage mechanism, so that the electrical connector assembly 10 is electrically connected to the battery end electrical connector of the battery pack.

[0100] In this embodiment, the charging connector device 100 rotates the rotating disk 30 around its connection end 302 by pressing down the rotating disk 30 with the battery pack. Then, the rotational motion of the rotating disk 30 is converted into the movement of the mounting base 40 moving closer to or away from the bearing end 301 of the rotating disk 30 through the linkage mechanism. Finally, the charging connector device 100 achieves automatic mechanical docking, so that the electrical connector assembly 10 and the electrical connector at the battery pack end are electrically connected. Compared with the prior art, which achieves electrical connection by converting the vertical movement into the horizontal movement of the mounting base 40, the structure of the charging connector device 100 in this embodiment has a rotation point, which is more stable when switching states and less prone to mechanical jamming during use.

[0101] like Figure 13As shown, furthermore, in order to simultaneously align and connect the battery-side liquid cooling assembly on the battery pack with the liquid cooling assembly on the charging rack, the charging connector device 100 also includes two liquid cooling assemblies 90 for connecting to the battery-side liquid cooling assembly on the battery pack. The two liquid cooling assemblies 90 are disposed on the mounting base 40 and located horizontally on both sides of the electrical connector assembly 10. The positions of the aforementioned liquid cooling assemblies 90 on the mounting base 40 correspond one-to-one with the positions of the battery-side liquid cooling assemblies on the battery pack.

[0102] Furthermore, to enable the electrical connector assembly 10 to float and adjust its position in a plane perpendicular to the movement direction M of the mounting base 40, thereby ensuring precise alignment between the electrical connector assembly 10 and the battery terminal connector, the mounting base 40 is also provided with a vertically arranged floating plate 901. The floating plate is floatingly connected to the mounting base 40 via horizontally arranged springs 902 and vertically arranged springs 902, and the electrical connector assembly 10 is mounted on the floating plate 901, i.e., connected to the mounting base 40 via the floating plate 901. The horizontally arranged springs 902 are used to achieve horizontal floating of the electrical connector assembly 10, and the vertically arranged springs 902 are used to achieve vertical floating of the electrical connector assembly 10.

[0103] Furthermore, one end of the mounting base 40 is provided with a sensor whose sensing direction is towards the bearing end 301 of the rotating disk 30. In this embodiment, the sensor is a photoelectric sensor. When the battery pack is placed on the bearing end 301 of the rotating disk 30, the photoelectric sensor is triggered, thereby determining that a battery pack is placed at the charging connector device 100. In this embodiment, the distance between the battery pack and the photoelectric sensor must be less than or equal to 15mm to be triggered.

[0104] In other specific implementations, other sensors may also be used, such as infrared sensors, ultraviolet sensors, Hall sensors, etc., which will not be elaborated here.

[0105] in, Figure 1 The diagram schematically illustrates the direction R of rotation of the bearing end 301 around the connecting end 302, i.e., clockwise or counterclockwise rotation around the connecting end 302. Meanwhile, Figure 1 The direction of movement M of the mounting base 40 is also schematically shown, that is, it moves along the bearing end 301 that is close to or away from the rotating disk 30. The following is an explanation of the rotation of the bearing disk and the movement of the mounting base 40.

[0106] When the battery pack is detached from the support end 301, the rotating disk 30 rotates upward with the connection end 302 as the rotation point (corresponding to clockwise rotation), and the mounting base 40 moves away from the support end 301 of the rotating disk 30 under the force provided by the reset component.

[0107] When the battery pack is placed on the support end 301, the rotating disk 30 rotates downward with the connection end 302 as the rotation point (corresponding to counterclockwise rotation), and the mounting base 40 moves towards the support end 301 of the rotating disk 30 under the force provided by the linkage mechanism, so that the electrical connector assembly 10 is electrically connected to the battery end electrical connector of the battery pack.

[0108] It should be noted that, Figure 1 and Figure 2 The diagram shows the rotating disk 30 in a supporting state and the mounting base 40 in a mating position, with a battery pack placed on the supporting end 301. At this time, the battery pack presses down on the supporting end 301 from top to bottom, and the supporting end 301 and the connecting end 302 are essentially on the same horizontal plane. Correspondingly, when the battery pack detaches from the supporting end 301, the supporting end 301 rotates upward around the connecting end 302 until the rotating disk 30 is in its initial state. At this point, the mounting base 40 is in its initial position, and the supporting end 301 tilts upward relative to the connecting end 302.

[0109] In other alternative embodiments, the positional relationship between the bearing end 301 and the connecting end 302 when the rotating disk 30 is in different states can also be set as follows: when the rotating disk 30 is in the initial state, the angle at which the bearing end 301 is tilted relative to the connecting end 302 is the first angle; when the rotating disk 30 is in the bearing state, the angle at which the bearing end 301 is tilted relative to the connecting end 302 is the second angle; wherein, the first angle is greater than the second angle, and the difference between the first angle and the second angle corresponds to the angle at which the rotating disk 30 rotates when the rotating disk 30 switches between the initial state and the bearing state.

[0110] The specific structure of the linkage mechanism is briefly described below with reference to the accompanying drawings.

[0111] like Figure 3-9 As shown, the linkage mechanism includes a linkage mechanism 50 and a horizontal moving mechanism 60. The mounting base 40 is slidably connected to the rotating disk 30 via the horizontal moving mechanism 60. The first end of the linkage mechanism 50 is rotatably connected to the bearing end 301 of the rotating disk 30, and the second end of the linkage mechanism 50 is rotatably connected to the mounting base 40. When the rotating disk 30 switches from the initial state to the bearing state, the linkage mechanism 50 converts the flipping motion of the rotating disk 30 into a force that moves the mounting base 40 from the initial position to the docking position.

[0112] It should be noted that in this embodiment, a linkage mechanism including a linkage mechanism 50 and a horizontal moving mechanism 60 is adopted. When the charging is completed and the battery pack needs to be removed, that is, when the battery pack needs to be detached from the support end 301, the rotating disk 30 rotates upward (clockwise). The rotating disk 30 rotates at a small angle, which allows the mounting base 40 to move a relatively long distance away from the support end 301. This allows the mounting base 40 to quickly move away from the battery end electrical connector of the battery pack, thereby preventing collisions or jamming caused by the mounting base 40 not being able to move away from the battery end electrical connector in time during the upward rotation of the rotating disk 30, thus improving the safety of the charging connector device 100.

[0113] To simplify the structure of the charging connector device 100, such as Figure 3-9 As shown, the linkage mechanism 50 includes a first link 501 and a second link 502. The first end of the first link 501 is rotatably connected to the bearing end 301 of the rotating disk 30, and the second end of the first link 501 is rotatably connected to the first end of the second link 502. The second end of the second link 502 is rotatably connected to the mounting base 40. The connection between the first link 501 and the second link 502 is slidably connected to the connecting seat 20. Furthermore, when the rotating disk 30 switches between its initial state and its bearing state, the angle between the first link 501 and the second link 502 toward the mounting base 40 is always less than or equal to 90°, i.e., an acute angle.

[0114] Regarding the connection between the first connecting rod 501 and the bearing end 301 of the rotating disk 30, as follows: Figure 11 As shown, a connecting block 303 is provided at the bottom of the bearing end 301 of the rotating disk 30, and the first end of the first connecting rod 501 is rotatably connected to the connecting block 303.

[0115] Accordingly, regarding the connection between the second link 502 and the mounting plate, as follows: Figure 2-3 , Figure 5-6 and Figure 8 As shown, the mounting base 40 is provided with a connecting portion 401 extending toward the connecting base 20, and the second end of the second connecting rod 502 is rotatably connected to the mounting base 40 through the connecting portion 401. In this embodiment, the connecting portion 401 is provided on the lower end surface of the connecting base 20.

[0116] In order to guide the movement of the connection between the first link 501 and the second link 502, the linkage mechanism 50 is configured to also include a sliding guide structure, and the connection between the first link 501 and the second link 502 is slidably connected to the sliding guide structure.

[0117] Specifically, such as Figure 2 , Figure 4-7 and Figure 9As shown, the connecting seat 20 includes a base plate 201, and the sliding guide structure includes a guide member 503 disposed on the connecting seat 20. The guide member 503 has a strip-shaped guide hole 504. The connection point between the first connecting rod 501 and the second connecting rod 502 is located within the guide hole 504 and can move along the length direction of the guide hole 504. In this embodiment, the guide member 503 is a straight plate and is vertically disposed on the base plate 201 of the connecting seat 20. The length direction of the guide hole 504 is parallel to the plane of the base plate 201. The guide hole 504 of the guide member 503 guides the movement of the connection point between the first connecting rod 501 and the second connecting rod 502, so that when the first connecting rod 501 is subjected to force, the force can be converted through the guide hole 504 into a force that drives the mounting seat 40 to move horizontally along the rotating disk 30, thus smoothly realizing the mechanical automatic electrical connection function of the charging connector device 100.

[0118] like Figure 2-8 As shown, the first end of the first connecting rod 501 is rotatably connected to the connecting block 303 via the first connecting shaft 505 (the connecting block 303 is provided with a first connecting hole 3031, and the first connecting shaft 505 passes through the first connecting hole 3031). The second end of the first connecting rod 501 is rotatably connected to the first end of the second connecting rod 502 via the second connecting shaft 506, and the second connecting shaft 506 passes through the guide hole 504.

[0119] The following is combined Figure 1-2 , Figure 4-9 The structure of the connector 20 will be further explained.

[0120] In addition to the base plate 201, the connecting seat 20 also includes a surrounding plate 202 circumferentially disposed on the base plate 201, that is, the surrounding plate 202 surrounds the edge of the base plate 201. The base plate 201 and the surrounding plate 202 together form a receiving cavity, and the rotating disk 30 is disposed at the opening of the receiving cavity. In this embodiment, the surrounding plate 202 is disposed perpendicular to the base plate 201, and the surrounding plate 202 can protect the internal structure of the charging connector device 100.

[0121] The following is combined Figure 2 and Figure 8 The structure of the horizontal moving mechanism 60 is described below.

[0122] like Figure 2 and Figure 8 As shown, the horizontal moving mechanism 60 includes a slidingly engaged guide rod 601 and a slider 602, wherein the extending direction of the guide rod 601 is parallel to the movement direction M of the mounting base 40 (shown in...). Figure 1 The guide rod 601 and the slider 602 are respectively connected to the rotating disk 30 (specifically connected to the adapter plate 305 of the rotating disk 30 mentioned below) and the mounting base 40.

[0123] like Figure 8As shown, there are two horizontal moving mechanisms 60, which are respectively located at both ends of the mounting base 40. The inclusion of two horizontal moving mechanisms 60 helps to improve the stability and reliability of the mounting base 40 when moving between its initial position and its docking position.

[0124] It should be noted that the number of horizontal moving mechanisms 60 is not limited to two. In other alternative embodiments, the number of horizontal moving mechanisms 60 can also be set to one, three or more, depending on actual needs.

[0125] like Figure 3-8 As shown, there are two linkage mechanisms 50 along the horizontal direction, with each linkage mechanism 50 corresponding to a connecting part 401. The linkage mechanism 50 is located between the connecting seat 20 and the rotating disk 30. Furthermore, the linkage mechanism 50 is situated between at least two horizontal moving mechanisms 60. This arrangement effectively utilizes the space between at least two horizontal moving parts, which helps improve the compactness of the charging connector device 100.

[0126] Of course, the number of linkage mechanisms 50 is not limited to two. In other alternative embodiments, the number of linkage mechanisms 50 can also be set to one, three or more, depending on actual needs.

[0127] The following is combined Figure 1-4 , Figure 11-12 The structure of the rotating disk 30 will be described below.

[0128] The rotating disk 30 includes a disk body 304 and an adapter plate 305. The disk body 304 has a receiving hole 3041 for the mounting base 40 to pass through, and the connecting end 302 and the bearing end 301 are the two ends of the disk body 304, respectively. The adapter plate 305 is disposed at the receiving hole 3041 of the disk body 304, and the adapter plate 305 is recessed toward the connecting base 20 to form a mounting area into which the mounting base 40 partially extends.

[0129] Specifically, the adapter plate 305 includes a first connecting plate 306 and a second connecting plate 309 connected to each other at a preset angle. The end of the first connecting plate 306 away from the second connecting plate 309 is connected to the receiving hole 3041 of the disk body 304, and the second connecting plate 309 is located on the side of the disk body 304 near the connecting seat 20. The mounting seat 40 is connected to the second connecting plate 309 through a horizontal moving mechanism 60 and partially extends between the disk body 304 and the second connecting plate 309. In this embodiment, both the first connecting plate 306 and the second connecting plate 309 are annular plate structures.

[0130] Specifically, to further increase the connection area between the adapter plate 305 and the disk body 304, thereby increasing the connection strength, the first connecting plate 306 includes an extension portion 307 in the form of a ring-shaped straight plate and a connecting body 308. The extension portion 307 is attached to and welded to the lower end face of the disk body 304. The connecting body 308 is connected to the receiving hole 3041 of the disk body 304 and connected to the second connecting plate 309. The guide rod 601 of the horizontal moving mechanism 60 is detachably connected to the second connecting plate 309 by fasteners 311. The extension portion 307 and the second connecting plate 309 are located on different sides of the connecting body 308. The preset angle between the connecting body 308 and the second connecting plate 309 is 90°, and the included angle between the extension portion 307 and the connecting body 308 is also 90°, thus forming a ring-shaped plate structure with a Z-shaped cross-section.

[0131] However, it should be noted that the structural form, cross-sectional shape, and angle between the connecting body 308 and the second connecting plate 309 of the adapter plate 305 are not limited to the above-mentioned aspects. In other alternative embodiments, they can be set according to actual needs. For example, in the preferred embodiment described above, the extension portion 307 of the first connecting plate 306 is a preferred setting to strengthen the adapter plate 305 and to facilitate the connection between the adapter plate 305 and the disk body 304. In alternative embodiments, the first connecting plate 306 can be set to only include the connecting body 308, that is, the cross-section of the adapter plate 305 is L-shaped.

[0132] like Figure 11 As shown, the rotating disk 30 is provided with a bent portion 310, which is located at the connecting end 302 of the disk body 304. The bent portion 310 is rotatably connected to the surrounding plate 202 of the connecting seat 20 via a connecting pin 70. In this embodiment, the bent portion 310 is arranged vertically along the circumference of the disk body 304, and both the bent portion 310 and the disk body are plate-shaped structures. The bent portion 310 is located in the receiving cavity of the aforementioned connecting seat. To facilitate the rotation of the rotating disk 30 relative to the connecting seat 20, at least one side of the bent portion 310 at both ends of the disk body 304 has a gap with the surrounding plate 202 of the connecting seat 20 (e.g., ...). Figure 2 (As shown). The connecting pin 70 enables reliable rotation between the rotating disk 30 and the connecting seat 20, which helps to ensure that the rotating disk 30 can reliably switch between the initial state and the load-bearing state, thereby improving the reliability of the charging connector device 100 in charging the battery pack.

[0133] Specifically, the bent portion 310 is provided with a first connecting hole 3031, and the connecting seat 20 is provided with a second connecting hole. Both ends of the connecting pin 70 are provided with circumferential flanges 701. The connecting pin 70 passes through the first connecting hole 3031 and the second connecting hole, so that the bent portion 310 and the connecting seat 20 are located between the two circumferential flanges 701. The circumferential flanges 701 of the connecting pin 70 can limit the gap or relative position between the rotating disk 30 and the connecting seat 20. That is, when the rotating disk 30 shifts to one side, the circumferential flanges 701 of the connecting pin 70 on the other side will prevent the rotating disk 30 from shifting further, thereby avoiding the increased friction caused by the bent portion hitting the surrounding plate when the rotating disk flips, and ensuring the flexibility of the rotating disk rotation.

[0134] like Figure 1 , Figure 4-7 and Figure 9 As shown, the connecting base 20 has connecting ear plates 203 extending horizontally in opposite directions at both ends. Each connecting ear plate 203 has a first position adjustment hole 204. The connecting ear plate 203 is detachably connected to at least one set of multiple sets of second position adjustment holes on the frame 200 via the first position adjustment hole 204 and the connecting assembly. The connecting ear plate 203 facilitates connection to the frame 200. The first position adjustment hole 204 on the connecting ear plate 203, combined with the second position adjustment holes, allows for convenient adjustment of the charging connector device 100's position to accommodate battery packs of different sizes, thereby expanding the applicability of the charging connector device 100.

[0135] In this embodiment, the connecting ear plate 203 is provided with a plurality of first position adjustment holes 204, and the first position adjustment holes 204 are detachably connected to the second position adjustment holes on the frame 200 by bolts.

[0136] The following is combined Figure 2-3 , Figure 5-6 and Figure 8 The structure of the reset component is illustrated in the figure.

[0137] Mounting base 40 is located between the bearing end 301 and the connecting end 302 of the rotating disk 30. The two ends of the reset assembly are connected to the connecting base 20 and the mounting base 40 respectively, so as to apply a force to the mounting base 40 toward the bearing end 301 away from the rotating disk 30. When the force of the battery pack on the bearing end 301 is removed, the reset assembly acts on the mounting base 40, causing the mounting base 40 to move toward the connecting end of the rotating disk, and then, under the action of the linkage mechanism 50, it drives the rotating disk 30 to rotate until it returns to the initial state.

[0138] The reset assembly includes an elastic element 80, which is in a stretched state when the rotating disk 30 is in its initial state. In this embodiment, the elastic element 80 is specifically a tension spring. The first end of the elastic element 80 is connected to the connecting portion 401, and the other end is connected to the surrounding plate of the connecting seat 20 near the connecting end of the rotating disk.

[0139] When the rotating disk 30 is in its initial state, the elastic member 80 applies a force to the connecting part 401 toward the bearing end 301 that is away from the rotating disk 30.

[0140] Specifically, when the force of the battery pack on the bearing end 301 is removed, the elastic element 80 provides a force to the mounting base 40 away from the bearing end 301 of the rotating disk 30. The mounting base 40 moves and drives the rotating disk 30 to rotate, eventually making the mounting base 40 in the initial position and the rotating disk 30 in the initial state.

[0141] It should be noted that when the rotating disk 30 is under load, the elastic element 80 of the tension spring is still under tension.

[0142] Furthermore, in this embodiment, there are two elastic elements 80, and the elastic elements 80 are arranged in a one-to-one correspondence with the connecting part 401. The two elastic elements 80 are arranged in the same direction between the connecting seat 20 and the rotating disk 30, that is, the two elastic elements 80 are arranged along the direction of movement M of the mounting seat 40.

[0143] In an alternative embodiment, the reset assembly can also be disposed between the rotating disk 30 and the connecting seat 20. Specifically, the two ends of the reset assembly are respectively disposed at the bearing end 301 of the rotating disk 30 and the connecting seat 20, so as to apply a force toward the bearing end 301 of the rotating disk 30 toward the connecting seat 20. When the force of the battery pack on the bearing end 301 is removed, the reset assembly acts on the bearing end 301, causing the rotating disk 30 to move, and then driving the mounting seat 40 to move under the action of the linkage mechanism 50 and the horizontal moving mechanism 60.

[0144] Accordingly, the reset assembly includes two elastic elements 80, which are arranged in the same direction between the connecting seat and the rotating disk. Figure 1The mounting base 40 is arranged in the direction of movement M. The elastic element 80 is vertically disposed between the bearing end 301 of the rotating disk 30 and the connecting base 20. The first end of the elastic element 80 abuts against the lower end face of the bearing end 301 of the rotating disk 30, and the second end of the elastic element 80 abuts against the bottom plate of the connecting base 20. The elastic element 80 is in a compressed state when the rotating disk 30 is in a bearing state. When the force of the battery pack on the bearing end 301 is removed, the elastic element 80 provides a force to the bearing end 301 of the rotating disk away from the rotating disk 30, so that the rotating disk 30 switches to its initial state and the mounting base switches to its initial position. In this embodiment, the elastic element 80 can be configured as a compression spring.

[0145] It should be noted that when the rotating disk 30 is in the initial state, the elastic element 80 of the compression spring may still be in a compressed state or exactly in the original state. The aforementioned original state means that the compression spring is neither compressed nor stretched.

[0146] Furthermore, in order to position the elastic element 80 in the horizontal direction, the base plate of the connecting seat 20 is provided with a positioning structure, which consists of a pair of positioning plates with an L-shaped cross-section. The two positioning plates are symmetrically welded to the base plate. Specifically, the elastic element 80 is fitted onto the vertical part of the two positioning plates.

[0147] In other specific embodiments, the positioning plate can also be set on the base plate by means of detachable connection such as bolts; the shape of the positioning structure is not limited to this example, and can also be a cylinder, square tube, cylindrical column, square column, etc. that matches the inner ring size of the compression spring; the number of elastic elements 80 is not limited to this example, and can also be one, three or more, which will not be elaborated here.

[0148] Based on the above, the following is a summary of the working process of the charging connector device 100 from the time the battery pack is placed into the battery pack to the time it is removed (i.e., during the battery pack charging process).

[0149] (1) Battery pack placement - Rotary disk 30 switches from initial state to load-bearing state, mounting base 40 moves from initial position to docking position.

[0150] When the battery pack needs to be charged, it is placed on the bearing end 301 of the rotating disk 30. The battery pack presses down on the rotating disk 30 from top to bottom. The bearing end 301 of the rotating disk 30 rotates downward relative to the connecting seat 20 around the connecting end 302 (counterclockwise). The downward rotation of the rotating disk 30 drives the first connecting rod 501 to rotate. The rotation of the first connecting rod 501 drives the second connecting rod 502 to slide relative to the guide hole 504 of the guide member 503 at the connection point of the two (i.e., relative to the connecting seat 20). The second connecting rod 502 acts on the mounting seat 40 through the connecting part 401, so that the mounting seat 40 moves from the initial position toward the bearing end 301 under the cooperation of the guide rod 601 and the slider 602 until the electrical connector assembly 10 is electrically connected to the battery end electrical connector of the battery pack. At this time, the rotating disk 30 is in the bearing state and the mounting seat 40 is in the mating position.

[0151] (2) Battery pack removal - Rotary disk 30 switches from self-supporting state to initial state, mounting base 40 moves from docking position to initial position.

[0152] When the battery pack is fully charged and needs to be removed, the force exerted by the battery pack on the bearing end 301 of the rotating disk 30 is eliminated. Under the action of the elastic element 80, that is, the elastic element 80 provides a force to the mounting base 40 away from the bearing end 301 of the rotating disk 30. The mounting base 40 moves from the docking position toward the bearing end 301 of the rotating disk 30. The movement of the mounting base 40 will drive the second link 502 to move through the connecting part 401, thereby driving the first link 501 to rotate, and further driving the bearing end 301 of the rotating disk 30 to rotate upward (clockwise) relative to the connecting base 20 around the connecting end 302 until the mounting base 40 returns to the initial position and the rotating disk 30 returns to the initial state.

[0153]

Example 2

[0154] like Figure 14 As shown, this embodiment provides a charging rack, which includes a frame 200 and a charging connector device 100 as in Embodiment 1. The charging connector device 100 is connected to the frame 200.

[0155] In this embodiment, the frame 200 includes at least two brackets 2001 for supporting the battery pack. A charging compartment for accommodating the battery pack is formed between two adjacent brackets 2001 in the height direction. The charging connector device 100 is provided in a one-to-one correspondence with the charging compartment and is connected to the bracket 2001.

[0156] The charging connector device 100 is connected to the bracket 2001 and is located at one end of the bracket 2001. The positions of the charging connector device 100 and the bracket 2001 are relatively fixed. When the battery pack is placed in place on the bracket 2001, the corresponding part of the battery pack will also be placed in place on the bearing end 301 of the rotating disk 30, so as to realize the reliable connection between the charging connector device 100 and the battery pack.

[0157] To accommodate battery packs of different sizes and thus expand the applicability of the charging connector device 100, at least two sets of second position adjustment holes (not shown in the figure) are provided on the bracket 2001 along the first direction (the mating direction between the battery end electrical connector and the electrical connector assembly 10). The first position adjustment hole 204 of the charging connector device 100 is detachably connected to the at least one set of second position adjustment holes via a connecting assembly. With this configuration, the position of the charging connector device 100 on the bracket 2001 can be easily adjusted via the first position adjustment hole 204 and the second position adjustment holes, thereby accommodating battery packs of different sizes and expanding the applicability of the charging stand.

[0158]

Example 3

[0159] like Figure 15 As shown, this embodiment discloses a battery swapping station, which includes a battery swapping area 300 and a charging area 400. The battery swapping station includes the charging rack in Embodiment 2, which is disposed in the charging area 400. Figure 15 The charging rack in the diagram is used to show its location within the charging area 400 and its relationship to other structures.

[0160] As an illustrative embodiment, the battery swapping station includes two charging areas 400 and one battery swapping area 300. Along the direction perpendicular to the vehicle's travel direction, the two charging areas 400 are located on both sides of the battery swapping area 300. Each charging area 400 is equipped with a charging rack, and the two charging racks are arranged in the same direction.

[0161] In addition, the battery swapping station also includes a battery transfer device 500 and a battery swapping device. The battery swapping device removes a depleted battery from the electric vehicle 600 and transfers it to the battery transfer device 500. The battery transfer device 500 then transfers the depleted battery to the battery compartment for charging. Afterward, the battery transfer device 500 removes a fully charged battery from the battery compartment and transfers it to the battery swapping device, which then installs the fully charged battery into the electric vehicle 600.

[0162] As an illustrative embodiment, the battery transfer equipment 500 uses a palletizer. After the palletizer removes the battery pack (depleted battery) from the battery swapping equipment through a double extension mechanism, the palletizer moves the battery pack upward to the corresponding charging compartment position and pushes the battery pack into the charging compartment from the side until the battery pack is placed in place.
